UK ONS report finds significant challenge remains to reduce road transport emissions; sector GHG emissions up 6% from 1990-2017

Green Car Congress

A new report by the UK’s Office for National Statistics (ONS) finds that greenhouse gas (GHG) emissions from road transport in the UK rose by 6% from 1990 to 2017. The increase—albeit lower than the increase in road traffic—highlights the significant challenge in reducing emissions from road transport, the report says.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets. C, or 1.8 ?F, F, since the late 1800s.).

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.

Study Measures the Effect of Fischer-Tropsch Synthetic Jet Fuel on Emissions

Green Car Congress

A comprehensive emissions performance test of a business-class aircraft gas turbine engine burning fossil JP-8 fuel, synthetic FT fuel, and a 50/50 JP-8/FT blend found that emissions of trace gases, soot particles, and nucleation/growth PM were directly impacted by the sulfur and aromatic content of the fuel. —Timko et al.

International automotive researchers emphasize the importance of continued development of the internal combustion engine

Green Car Congress

The editorial addresses important issues in the current politically charged discussions of global warming and climate-change alarm. … It is very likely that highly efficient “fully flexible” engines with hybridized solutions will be a big part of sought-after efficiency improvements, as well as emission/GHG reductions.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

A new study quantifying emissions from a fleet of gasoline direct injection (GDI) engines and port fuel injection (PFI) engines finds that the measured decrease in CO 2 emissions from GDIs is much greater than the potential climate forcing associated with higher black carbon emissions from GDI engines.
